Calculate Tan 15

Introduction & Importance

Calculate tan 15 is essential in trigonometry, physics, engineering, and other fields. It helps determine the ratio of the opposite side to the adjacent side in a right-angled triangle with an angle of 15 degrees.

Formula & Methodology

The formula for tangent is opposite/adjacent. For an angle of 15 degrees, we use the tangent value from the unit circle or a calculator.

Real-World Examples

Case Study 1

In a right-angled triangle, if the adjacent side is 5 units, the opposite side is 5 * tan(15°) ≈ 4.24 units.

Case Study 2

If the opposite side is 3 units, the adjacent side is 3 / tan(15°) ≈ 7.07 units.

Case Study 3

To find the hypotenuse, use the Pythagorean theorem: hypotenuse = √(adjacent² + opposite²)
